Application filed February 28, 1907. Serial No. 359,764.

To a/ZZ whom t n1/ty concern:

Be it known that I, JOSEPH C.' HOLLINGS- WORTH, a citizen of the UnitedStates, residing at Dallas, in the county of Dallas and State of Texas,have invented certain new and useful Improvements in Gin-Saw Oleaners,of which the following is a specification.

This invention relates to improvements in gin saw cleaners for use inconnection principally with cotton gins and the like.

'In general, the objects of the invention are to provide a device of thecharacter mentioned for cleaning the saws of a cotton gin when they havebecome gummed or fouled, said device being capable of being applied tothe alternate spaces between the saw blades, whereby the saws will havean opportunity7 to yield in the case of bent teeth and to provide adevice capable of being readily used in connection with any of the usualforms of cotton gms.

With these and other objects in view, the invention consists in themechanical elements, or their equivalents, to be hereinafter describedand claimed.

In the accompanying drawings, wherein similar letters of reference areused to indicate corresponding parts in each of the several views,Figure 1 is a plan view of the cleaner arranged in position foroperation on the saws; Fig. 2 is a side elevation of the cleaner; Fig. 3is a section on the line 3 3, Fig. 2, and Fig. 4 is a fragmentary detailview of the cleaning end of one ofthe teeth of the cleaner.

Broadly speaking, the cleaner comprises a pluralityl of adjustablecleaner teeth, a suitable holder for said teeth, retaining means formaintaining said teeth in the adjusted positions and a suitable devicefor locking said retaining means in its operative position.

In the drawings, A indicates theholder as an entirely, comprising a baseplate A made preferably of sheet metal and bent upon itself to present asupporting edge a and a guiding flange a at its opposite edgesrespectively. The flange a is bent over into substantial parallelismwith the main portion of the base plate A, thus forming a slide way a2for the feet of the adjustable teeth B of th cleaner, as clearly shownin Fig. 3.

C indicates an L bar securely attached to the base plate A as by rivetsc with its upright face C close to the mouth of the slide l way 0,2,whereby the teeth are braced and held against forward movement.

The teeth B are formed with feet b adapted to travel in theafore-mentioned slide way a2, a face portion b adapted to bear againstthe upright face C of L bar C, and a blade portion b2. The blade sectionterminates ina dished portion t3 having convergent sharpened edges b4adapted to bear against and clean the faces of the several sawsindicated herein at X of the cotton gin.

From the construction thus far described, it will be obvious that theteeth B to any desired number may be readily slid into the holder A andplaced in any desired position therein, dependent upon the machine to becleaned. In order to prevent movement of the .teeth B after they havebeen adjusted to the desired position, a retaining bar is used. Theretaining bar comprises an upright face plate D and an attached bar D,the said bar and face plate being connected by rivets d or the like. BarD runs longitudinally of the face plate and at one end is bentsubstantially at right angles to the same, as at d. This downwardlyturned portion d passes through an opening a2 in base-plate A andthereafter is again bent to form a toe d2 which takes against the underside of baseplate A. It will thus be seen that the above constructionforms a detachable pivot connection for the retaining `bar D whereby thesame may be swung into or out of operative position or entirely removedat will.

For positively locking the retaining bar D in its operative position, alever E is slidingly fulcrumed on bar D. Lever E comprises an operatingarm E, an arm e adapted to act as a sliding fulcrum on bar D, and an arme terminating in a hook e2 adapted to engage an eye "f in post F whichis attached to base plate A. i

It will be observed that if desired the lever E may be entirely detachedby simply turning it in a direction away from plate D and removing thehook c from the eye In order to positively lock bar D in operativeposition, it is only necessary to turn lever Fin an opposite directionuntil it reaches the position shown in full lines in Fig. 2, thusforcing bar D down tightly on the cleaner teeth. When in its depressedor locking position, it is held therein by an ear d2, or similar means,attached to plate D. An opening IOO or notch d3 is provided in plate Dto give ready access to the handle of arm E of lever E and at the sametime to allow of its lying wholly within the plane of plate D.

As clearly shown in Fig. l, the teeth of the cleaner are adjusted to liein alternate spaces only of the saws and not between every two saws. thecleaner teeth are then adjusted and placed in position for cleaning theother set. This is an important feature in the practical application ofsaw cleaning devices of this nature. By so placing the cleaner teeth,sidewise or lateral movement of the saws relative to said teeth ispossible. Thus, when the cleaner teeth meet with a bent or crookedsaw-tooth, the saw blade is defiected to one side and not injured bysuch contact. On the other hand, where the cleaner teeth occupy all ofthe intervals between saws, it is impossible for such saws to bedeflected when a crooked saw tooth is intercepted by a cleaner toothand, consequently, much damage is done to the saws, cleaners andmachinery in general g the cleaner tooth would break off the bent toothor the saws would have to be stopped and the machine withdrawn andreplaced above the obstruction. As a matter of fact, machines whereinthe cleaner teeth are placed in every space instead of every alternatespace, as in my improvement, are not practical in use and are failuresfor the reasons stated.

It will be understood, of course, that the invention is not limited tothe exact construction herein shown and described, as various changesmay be made therein without departing from the spirit and scope of myinvention.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States is:

l. A saw-cleaner comprising a plurality of cleaner teeth, a holder forsaid teeth, means for retaining said teeth in their adjusted posi tionsand means for locking in position said retaining means.

2. A saw-cleaner comprising a plurality of adjustable cleaner teeth, a-holder for said teeth, a rod or plate for retaining said teeth in theiradjusted positions and means for locking in position said retainingmeans.

3. A saw-cleaner comprising a plurality of adjustable cleaner teeth, aholder for said teeth, pivotally mounted means for retaining said teethin their adjusted positions and means for locking in position saidretaining means.

4. A saw-cleaner comprising a plurality of cleaner teeth, a holder forsaid teeth, means for preventing forward movement of said ,When one set.of teeth are cleaned,

teeth, means for retaining said teeth in their adjusted positions andmeans for locking in position said retaining means.

5. A saw-cleaner comprising a plurality of cleaner teeth, a holder forsaid teeth, a pivotally mounted bar adapted to hold said teeth in theiradjusted positions and means for locking said bar in operative position.

6. A saw-cleaner comprising a plurality of cleaner teeth, a holder forsaid teeth, a pivotally mounted bar adapted to hold said teeth in theiradjusted positions and a locking lever, whereby said bar is forced intoand held in operative position.
